For enhanced safety, the front seat shoulder belts of the Mercedes CLA EQ are height-adjustable to accommodate a wide variety of driver and passenger heights. A better fit can prevent injuries and the increased comfort also encourages passengers to buckle up. The BMW i4 doesn’t offer height-adjustable seat belts.
The CLA EQ has a standard front seat center airbag, which deploys between the driver and front passenger, protecting them from injuries caused by striking each other in serious side impacts. The i4 doesn’t offer front seat center airbags.
Earlier warning of stopped traffic, traffic signals, dangerous road conditions, weather, or accidents, can keep driver's safer and prevent crashes. The CLA EQ has Car-to-X Communication, a system that seamlessly communicates important warnings to the driver about impending danger, if they're available. The i4 doesn’t offer a system that can receive automated systems from infrastructure or other vehicles.
Both the CLA EQ and i4 have rear cross-traffic warning, but the CLA EQ has Active Brake Assist (automatically applies the brakes) to better prevent a collision when backing near traffic. The i4’s Cross Traffic Warning doesn’t automatically brake.
Both the CLA EQ and the i4 have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, front seatbelt pretensioners, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, post-collision automatic braking systems, daytime running lights, lane departure warning systems, blind spot warning systems, rearview cameras, rear cross-path warning, driver alert monitors and available around view monitors.
